Проблем с направата на thumbnail с codeigniter

[smoke]

Имам проблем със създаването на thumbnail с codeignitr:

Дава този error:

The path to the image is not correct.
Your server does not support the GD function required to process this type of image.

$config['image_library'] = 'gd2';
		$config['source_image']	= $this->session->userdata('news_upload_image')."111.jpg";
		$config['new_image']	= $this->session->userdata('news_upload_image')."thumb/";
		$config['create_thumb'] = TRUE;
		$config['maintain_ratio'] = TRUE;
		$config['width']	 = 75;
		$config['height']	= 50;

		$this->load->library('image_lib', $config); 
		$this->image_lib->resize();
	
		echo $this->image_lib->display_errors();

ето ти част от код за ресаиз на снимки
мога да ти прата и целия код, малко променен спрямо оргинала от нета.

<?
-----------------
      $simg = imagecreatefromjpeg("$idir" . $url);   // Make A New Temporary Image To Create The Thumbanil From
      $currwidth = imagesx($simg);   // Current Image Width
      $currheight = imagesy($simg);   // Current Image Height
      if ($currheight > $currwidth) {   // If Height Is Greater Than Width
         $zoom = $twidth / $currheight;   // Length Ratio For Width
         $newheight = $theight;   // Height Is Equal To Max Height
         $newwidth = $currwidth * $zoom;   // Creates The New Width
      } else {    // Otherwise, Assume Width Is Greater Than Height (Will Produce Same Result If Width Is Equal To Height)
        $zoom = $twidth / $currwidth;   // Length Ratio For Height
        $newwidth = $twidth;   // Width Is Equal To Max Width
        $newheight = $currheight * $zoom;   // Creates The New Height
      }
      $dimg = imagecreate($newwidth, $newheight);   // Make New Image For Thumbnail
      imagetruecolortopalette($simg, false, 256);   // Create New Color Pallete
      $palsize = ImageColorsTotal($simg);
      for ($i = 0; $i < $palsize; $i++) {   // Counting Colors In The Image
       $colors = ImageColorsForIndex($simg, $i);   // Number Of Colors Used
       ImageColorAllocate($dimg, $colors['red'], $colors['green'], $colors['blue']);   // Tell The Server What Colors This Image Will Use
      }
      imagecopyresized($dimg, $simg, 0, 0, 0, 0, $newwidth, $newheight, $currwidth, $currheight);   // Copy Resized Image To The New Image (So We Can Save It)
      imagejpeg($dimg, "$tdir" . $url);   // Saving The Image
      imagedestroy($simg);   // Destroying The Temporary Image
      imagedestroy($dimg);   // Destroying The Other Temporary Image
